What does the Particle Theory state about matter?

The Particle Theory states that all matter is made up of very small particles. This fundamental concept in chemistry explains that everything around us, regardless of its state – solid, liquid, or gas – is composed of tiny, indivisible particles. These particles are constantly in motion and interact with one another through various forces.

Understanding this theory helps in comprehending the behavior of materials in different states, such as how solids maintain their shape due to closely packed particles, whereas liquids take the shape of their container because the particles can move past one another. Gases, on the other hand, consist of particles that are far apart and move freely, resulting in a fill of the entire volume of their container.

The other options do not accurately reflect the principles of the Particle Theory. For example, the assertion that all matter is invisible misrepresents the concept, as many materials can be seen, though they are composed of small particles. Similarly, the notion that all matter consists of very large particles is incorrect since the theory specifically emphasizes that matter is made up of tiny particles. Finally, the idea that all matter can be observed with the naked eye does not hold true, as many particles and even atoms cannot be seen without specialized equipment. Thus, the correct understanding of
